FOLDING sLEn.

Specification of IlettersPatent.

Application filed December 16, 1918. Serial No. 266,883.

To all whom it may concern.

Be it known that I, CHARLES ALDRICH, a citizen of the United States, residing at West Paris, in the county of Oxford and State of Maine, have invented certain new and useful Improvements in Folding Sleds;

and I do hereby declare the following to. be,

a full, clear, and exact description of the invention, the art to which it appertains to make and use the same.

This invention relates to sleds and more particularly to a folding, or collapsible sled.

It is one of the objects of the present invention to provide a simple, practical, ineX- pensive and substantial and collapsible sled and to provide means for locking the sled sides or frames in extended position when the parts are set for use. 4 a

With the above and other objects in view as will be rendered mainfest in the following specification with relation to the'enr bodiment of the invention illustrated in the accompanying drawing, the invention consists in the construction, combination, and in details and arrangement of parts as more particularly hereinafter described.

In the drawing,

Figure 1 is a perspective view of the extended sled adjusted for use. p

Fig. 2 is a perspective view'ofthe sled showing it in collapsed position. I V

Fig. 3 is a bottom plan view of the extended sled frame, and, I

Fig. 4 is a detail fragmentary view of the knuckle-joint of theibrace.

The sled comprises a pair of side or frame members 2'-2 which may be of suitable ma terial of any desired proportion and dimension, these sides being connected by a series of transverse links 3, whi'chare arranged in pairs as clearly shown in Fig. 1. .The transverse links are pivotally connected to the sides or frames andare adaptedv to swing in parallelism so as toseparate the frames or sides from. each other, .as'shown in Fig. 1, as to permitthe collapsing of the sled to the position shown in Fig. 2.

While the sides or frames may be constructed in various manners, as illustrated each side or frame comprises a runner 5,

upper: ends of the as clearly shown such/as will enable others skilled in and mounted upon the pegs portion of the side or bled elements may be .position and for which they may swing,

the links of each pair 3 series of perpendicular pins on its face,.thefends of each runner bent up and secured to the upper'part of the pins, rails having its front and rear ends turned up at 6'and 7 to be secured to the upper portion of perpendicular pins 8, a-suitable number of wh ch s provided along the top surface of the runner 5 of each side or frame.

in Fig. 1, to receive the pairs of links: Extended along or pins on each runner, is a top or rail member '9, forming a frame 2, and in the illustration of my invention the rails or top ends of the members 9 are interposed between the re-' spective links of each pair, where they are mounted on the pins.

Thelinks or assemprevented from having longitudinal movement any suitable fastening means as for instance, cotter pins 10.

-For'the purpose of locking the swinging or pivotally connected sides or frames 22 in extended position I provide a simple knuckle-jointed link 11,- the ends of which are pivoted at 12 and 13, at diagonally opposite points When the in Fig. 1,

to certain sets of pairs oflmks.

the link 11 occupies a diagonal the purpose of collapsing the sled the link may be broken about its pivot 15 at the knuckle 14, so that the sec tions' will swing with respect to each other.

' I claim:

1. A laterally collapsible sled comprising side frames, a series of-parallel pairs of superposed links .connecting'the frames transversely at their, upper portions and upon ing the frames in extended relation.

2. A laterally collapsiblesled, comprising side frames, pairs of links connecting the frames transversely at them upper portions and upon which they may swing, and means for locking-the frames in extended relation, being spaced by components of the frames. 7

3. A laterally collapsible sled comprising side frames, each having a runner with a mounted on the pins andforming parts of Patented Apr; 8 1919. v

along the pin by and means-for lock- '55 The pin may be turned down,

side frames are spaced as shown the frames, pairs of links pivoted on the pins of and connecting the frames and 7 means for locking the extended frames.

p 4. A laterally collapsible sled comprising side frames, each having a runner with a series of perpendicular pins on its upper face, the ends of: each runner bent up and secured to the upper part of the pins, rails Copies of this patent may be obtained for mounted on the pins and forming parts of five cents each, by addressing the "Commissioner of Patents, Washington, D.
